Fieldmaster offers a wide range of hydraulic side shift bases for post drivers. The range of varying sizes and compact designs enable these bases to be used on most post driver brands. The specially designed range of vineyard bases was a direct result of working with vineyards who required something different to what the market currently offered! There is also the option to enable 4-way side shift on these models meaning the unit is able to move both across the back of the tractor and towards and away from the cab. The minimum required hydraulic oil flow for this machine is 16ltrs per minute.
